Caleb

Gee, I'm jealous. I really wish I'd painted this.

Anyhoo, upon further inspection, I noticed a couple other tiny things. But I think your handling of him is downright lively so I'm hesitant to say anything. Are his pupils two different sizes? And is the dark part of his iris a little different in each eye? Also, the hard edge of the triangular cast shadow from the bridge of his nose could probably be softened on the left (nose side) to turn the form of his nose more, and let the far edge of that shadow on his cheek do all the heavy lifting for you.

Your pictures are turning out really dark lately. Did you recalibrate your monitor or something?
